Three senior dogs get the chance to spend their golden years in loving homes. A 12-year-old cattle dog mix named Buster could be the perfect match for a doctor who has his heart set on adopting an older dog. A 10-year-old kelpie mix named Milo might be the best friend a man is looking for. And Dewy, a 12-year-old Tibetan spaniel, could be a great companion for a retiree.
